Silent Valley National Park, Palakkad

Believed to be the sole surviving bit of evergreen forest in Sahya Ranges, the Silent Valley National Park is situated around 40 km from Mannarkkad, Palakkad district, north Kerala, India. Explored by the botanist Robert Wight, the national park is part of the Western Ghats, a UNESCO World Heritage Site.

Locally known as Sairandhrivanam, one of the peculiarities of Silent Valley Forest is that it is devoid of the chirping of cicadas. Located in the core of the Nilgiri Bio-reserve, the Silent Valley National Park is probably one of the most magnificent gifts of nature to mankind. The River Kunthi descends from the Nilgiri hills, from an altitude of 2000 m above sea level, flows through Silent Valley before merging into Bharathapuzha River.

Silent Valley is also home to the largest population of Lion-tailed Macaque, an endangered species of Primate, in India.
